Relationship between improvement in GNRI, a nutritional index, and improvement in motor FIM in elderly stroke patients hospitalized in a Kaifukuki Rehabilitation Ward. Jpn J Compr Rehabil Sci 2016; 7: 7-12.Objective: To clarify the relationship between improvement in the Geriatric Nutritional Risk Index (GNRI) and improvement in the Functional Independence Measure (FIM).Methods: The subjects were 155 patients aged 65 years or older selected among stroke patients admitted to a Kaifukuki Rehabilitation Ward. Seven items, including GNRI at hospital admission and degree of GNRI improvement, served as independent variables. For multiple regression analysis, motor FIM score at hospital discharge was the dependent variable. For multiple logistic regression analysis, motor FIM gain (1:13 points or more, 0:12 points or less) was the dependent variable.Results: GNRI at admission was a significant positive independent variable in the multiple regression analysis. GNRI at admission and degree of GNRI improvement were both significant independent variables in the multiple logistic regression analysis, with odds ratios of 1.084 and 1.090, respectively.Conclusion: Improvements in motor FIM are greater when GNRI at admission and the degree of GNRI improvement are larger.
